CORD IMPELLED ROTATABLE DISK TOY Filed March 11, 1950 Inventor DOUGLAS ABAKER bywM Patented Jan. 13, 1 953 or Pics Douglas A. Baker, Ottawa,Ontario, Canada Application March 11, 1950, Serial No. 149,114

1 Claim.

This invention relates to improvements in a toy and appertainsparticularly to a cord-impelled disk or rotor that I call a racingwheel.

An object of the invention is to provide a rotatable disk-like memberthat may be easily spun at a high velocity and dropped to the ground torace away on its circumferential periphery.

A further object of the invention is to provide a toy racing wheelrotatable on and slidable Off a handle-carried shaft.

A further object of the invention is to provide a rotatable disk havinga novel hub structure providing evenly balanced winding drums onopposite sides and an axial bore therethrough to accommodate aWithdrawable axle shaft insertable from either side.

A still further object of the invention is the provision of a racingwheel toy of the nature and for the purpose described, characterized bystructural simplicity, durability and low cost of production and capableof affording children endless pleasure and interest and an opportunityto develop skill and manual dexterity in its operation.

To the accomplishment of these and related objects as shall becomeapparent as the description proceeds, the invention resides in theconstruction, combination and arrangement of parts as shall behereinafter more fully described, illus trated in the accompanyingdrawings, and pointed out in the claim hereunto appended.

The invention will be best understood and can be more clearly describedwhen reference is had to the drawings forming a part of this disclosurewherein like characters indicate like parts throughout the severalviews.

In the drawings:

Figure 1 is a perspective view of the assembled toy, with an impellingcord wound thereon;

Figure 2 is a front elevation of the racing wheel and removable handle;

Figure 3 is a side elevation of the racing wheel alone; and

Figure 4 is an enlarged sectional detail of the hub assembly as taken online 44 of Figure 3, looking in the direction indicated by the arrows.

In the present embodiment of the invention, the racing wheel is seen tocomprise a relatively thin stiff disk I of cardboard, synthetic plasticor the like that is intended to run along the 2 ground on itscircumferential periphery 2, here shown as having an irregularity in theform of a hump or cam 3. This peripheral irregularity will cause thewheel to leap or jump in its travel and. may be dispensed with ifdesired as a true disk can be made to travel farther.

Centrally the disk l is provided with a hub 4, that extends laterallyfrom both sides thereof in the form of a spool or drum with a coaxialbore 5 extending therethrough. This hub is actually formed of a pair ofdrum parts 4* and 4 the former having a trunnion 4 on one end thatextends through a perforation 6 in the centre of the disk and receivesthe companion annular drum part A on the proiecting length of thetrunnion; the disk I and the hub parts 4 and 4 being securely united inan assembly as shown clearly in transverse section in Figure 4.

The handle consists of a length of rod 1 that may be readily grasped inone hand and includes a pin 8 of reduced diameter continuing from oneend and of a size to fit easily in the bore 5 in the wheel hub 4.

In use, an impelling cord 9 is wound on either side of the hub 4 and ineither direction and with the hub mounted on the handle pin 8, and withthe handle held substantially horizontal or the pintle-like axle shaftslightly elevated, the cord is given a quick pull causing the wheel tospin rapidly on the axle shaft of the handle when the fast revolvingwheel is forced longitudinally off the pin 8 by a flip of the finger andthe freed wheel races in leaping fashion along the ground.

From the foregoing description taken in connection with the accompanyingdrawings, it will be manifest that a toy is provided that will fulfillall the necessary requirements of such a device, but as many changescould be made in the above description and many apparently widelydifferent embodiments of the invention may be constructed within thescope of the appended claim, without departing from the spirit or scopethereof, it is intended that all matters contained in the saidaccompanying specification and drawings shall be interpreted asillustrative and not in a limitative or restrictive sense.

Having thus described the invention, what is claimed as new is:

A freely running, rotatable and freely leaping toy comprising a hub anda disk having a peripheral protrusion seated on said hub, said hubhaving an enlarged shoulder portion on one side of the disk and areduced trunnion portion on the other side thereof, said disk beingseated on said trunnion portion against the shoulder portion; asupplemental hub portion coextensive in external diameter and lengthwith the enlarged shoulder portion, said supplemental hub portion beingseated on said trunnion portion to secure said disk on said hub andbalanc same on each side of said disk; an impelling cord windable aboutsaid hub on either side of said disk; an axial bore extending throughsaid hub; a handled shaft insertable into said bore from either end tosupport said toy while it is being rotated, said disk running andleaping freely on its periphery '4 when released from said shaft afterhaving been started running by said cord.
